At least six other voting locations remained open hours past 7 p.m., including West Gray, Acres Homes, Alief, Jersey Village, Champion Forest and Cypress.

More than 20,000 ballots had been cast on Friday, the final day of early in-person voting before Tuesday's elections.

As of 10:04 p.m., 700,019 ballots had been cast in the two weeks of early voting at the county's 37 locations. That number grew by nearly 3,000 from 8 to 10 p.m.

Daily in-person voting totals in Harris County have exceeded 50,000 in nine of the last 12 days. On Friday by 10 p.m., nearly 22,000 voters cast ballots.

"By law, if any voter is in line by 7 p.m., they are allowed to vote. That's why the voting is still going right now," said Du-Ha Kim Nguyen, voter outreach coordinator at the Harris County Clerk's office.
